+# Purpose : Keep pacman's mirrorlist on mirrors that are up to date with Arch.
+#           A mirror that stops syncing doesn't cause an error: update and
+#           version just stop seeing new packages, such as a new kernel.
+#
+# reflector.timer picks fresh mirrors once a week, and update picks new ones
+# straight away when the first mirror falls a day behind (updates.d/10-pacman.sh).
+# To choose mirrors yourself, edit /etc/xdg/reflector/reflector.conf: once it
+# doesn't start with the CoreDesktop line below, this leaves it alone. To stop
+# CoreDesktop changing the mirrorlist at all, add reflector to
+# ~/.config/coredesktop/skip-packages.
